The concept of a world government refers to a single political authority overseeing all of humanity, envisioned in various forms ranging from democratic to authoritarian. Philosophers such as Kant and Wendt discussed its viability, focusing on collective security and sovereignty, while authors like Scott Nearing emphasized its potential to tackle global challenges by differentiating between local and international concerns.
H.G. Wells pictured a global legal system under such a governance structure, and Victoria Woodhull associated it with societal advancement. The United Nations, despite its constraints, remains the nearest approximation, illustrating continuing discussions about its need, structure, and the steps necessary for its development.
